That's the price you pay for telephone access to an asset of value. I used to think
DVC was a big heavy-handed until I had to call my broker to get some money out (instead of putting it in :; ). I almost had to email a blood sample.
The alternative is either blind trust that you are who you say you are, or having DVC issue a password - which you know 90% of people would forget and cause a 10% increase in MS calls for 'password' issues
It will be nice when (if

) we can do a lot of basic operations online....
